Be it lmown that I, ERNEST LINCOLN SAGE,

-ia citizen of the United States, and resident of VNewton Center, .in the county .of-Mlddlesex controllers, and has for its object and ai'm to provide a device of the general character referred to of improved construction and etilcient in operation, all of which will best vbe understood from the following description,-

taken in connection with the accompanying drawings',- of one form or embodiment oi invention hereinafter to V)be describedrelates to fluid pressure or iow regulatorsvor lar 14 of the sleeve 12 and vat its other end v Specication of Letters Patent. Patented Apli'. 20, 1*.95. I

upon a collar 18 provided uponthe member 6 near the lower orouter end of the latter.

The upper end of the spindle 10 extends into" the lower end of a sleeve-like` member 20,

similar'to the sleeve 12, slidingly mounted in the casing 2. above the annular collar 4,

' and is there pivoted to' a pin 22 extending across the bore of the sleeve 20 and having lts endsxed in the. walls of the latter, as

shown Vin Figs. 3 and 4.l The Sleeve 20 slidingly surrounds a member 24, provided with an axial bore 26, open at its upper or outer end and closed at its lower or inner end, as shown in Figs. 3 and 4. The sleeve 20 and the member 24 are surrounded by a helical spring 28, bearing at one end upon a collar 30 provided on the upper or outer end of the member 24 and at the other end upon a collar 32 provided on'the lower or inner end of means forcarrying the inventioninto prac-e the Sleeve 20. The spring 28 tends to separate the slee've 20 and member 24, such action tical effect, whilevthe scope of the invention will be more particularly pointed outin the appended claims. v

In the drawings: Figure 1 isa ,sectional elevation of a, preferred form of regulator embodying my invention; Fig. 2 is a plan view thereof Fig. 3 is a centra-l longitudinal 's section in a plane perpendicular to the plane 0 of the latter ligure, with the parts in the same position as in the latter figure; Fig. 4

is a central longitudinal section similar t o Fig. 3,' but with the parts in different poslf 1 tion; Fig.5 is a cross section on line 5-5 of Fig. 4, and Fig. 6 c e or Fig. 4,.-

Sumlar' reference is a cross section on line numerals indicate corresponding'parts in all of the iiguresof the drawings,

of said spring being limited by contact of ythe collar 32 of the sleeve 20 with the annuaction of said spring being limited by contact of the .collar 32 of the sleeve 20 .andthe collar 14 of the sleeve 12 respectively Awith opposite sides of the annular shoulder 4 on In the' preferred embodiment of my in-A operative parts are contained in a preferably cylindrical tubular casing 2 provided inte- 4riorly with an annular shoulder 4. Referring t9 Fig.` 1, there is slidingly mounted in the casing 2, below-the shoulder 4, a member 6, boredaxially at 8., as Shown in Figs. 3, 4

and .6, from its lower end but closed at the upper endjwhere it terminatesA in a solid spindle 10. Themember 6 telescopes in a sleeve-like member 12 having, at its upper end, an exterior collar or shoulder 14, and it and the member 6. are surrounded by a helical spring 16, bearing at one end upon said col-- .vention selected for illustrative purposes, the v A'the inside of the casing 2.

It willbe readily .seen that with the construction so'far described, and nothing more,

very little if any fluid entering at theend E of thepapparatus would pass through it,

as for all practical purposes, and 4particu-l larly in the case of liquids, the collars 18, 14, 32. and 30, may be considered to be a close fit in the casing 2, the amountthat migln.v pass around said collars being negligible 'as regards the effect that it might have upon the object that it is sought to obtain by the present invention. Accordingly` the invention contemplates the provision of openings for the passage of 'luid, and which will cooperate with the partsso far described or their equivalents, to enable the pressure of the fluid to be controlled orregulated, asA

. collarsv 18 and 32, 'while all, three of those onv will hereinafter lbe more particularly 'described.

The embodiment of the invention herein described and illustrated in the drawings as 'The collars 1,8, 32 and 30 'on the members e 6, 20 and 24 respectively are each provided member 6, where lit H-ows-v up around the spindle 10 and out of the upper end of the i sleeve 'memberl12 intothe space betweenthe collars 14 and 32 .on the. sleeve members 12 with three grooves or slots lextending longi.

tudinally thereof and herein designated by the reference numerals 36, 38 and 40 respectively, theslots upon each collar being preferably4 disposed at substantially equaldistances from each other. Only two of these slots are illustrated lin the case' of the the collar 20 are' illustrated in Fig. 2. The member 12 is provided with two openings inthe form of tw'o longitudinally extended vslots or slits 42, 42 upon oppositel sides thereof, extending from a ,point near its lower end upv a short distance into the collar 14. Each of the members 6, 20 and 24 is provided with two openings in the form of two transverse slots 44, 44, 46, '46, and. 48, 48 upon-opposite sides of said members rev spectively.

The devi-ce 'is provided at aber end with interiorly screw-threaded portions 50, 52 to enable it to be connected to or inserted inthe apparatus in which it isl to be used, it being understood that the Huid, the pressure lof which is to be controlled or regulated, must enter' the device by the end Eand leave it by the end D.

The operation of the device will now be described. j

-` With the parts in-they position shown in Figs. 1l and 3, the Huid, in the illustrated example water, enters the casing 2 at lthe end E and Hows through the three slots 36 of the. collar .18 into the space between the collar 18 and the collar 14 on the member 12.

The water also Hows into the axial'bore 8 of the -member 6 and` out, into the space between' the two collars 18 and `14, through the slots 44, 44 providedin the member 6, said slots being below the lower end of the sleeveI member 12, when the parts are fn this position. From the space between the collars 18 and 14 thev water Hows through the longitudinal slots 42 of the sleeve member 12 into that part of the bore of the latter situated above the closed inner end of the and- 20 respectively. From this space the water Hows on the one hand through the slots 38 'of said collar 32 andion the other'` hand through that portion of the bore of Athe sleeve member 20 below. the closed inner end of the member 24 and through the slots I46 'of said sleeve member 20, into the space between4 the collars 32 and 30 of the sleeve member 20 and member 24 respectively. From this space the water Hows through the -slots 40 of the collar 30 and through the slots 48 of the niember 24 and the bore 26 of the latter out of the device through the openings in the foraminous disk 34. Ifthe pressure of the water entering the device in creases, the increased pressure acting on the collar 18 will move the member 6 yupwardly and with it the4 sleeve20, said parts, it will be remembered, being connectedV by the'spin- Y dle 10 of the member 6 and the pivot l'pin 22. f

The portion ofthe member 6 bearingfthe slots 44-is thus caused to enter the sleeve 12 and the sleeve20 iscausedto slide up over the slots 48 in the member 24, while the closed inner end of said member now extends below the slots 46 in the sleeve 20, thismovement ofthe member Gand sleeve 20.tak ing place against the pressure of the vsprings 16 and '28'.- The slots 44 in the member 6, the l slots 48 in the member 24 and the Slots 46 in the sleeve 20 now being closed,

water can enter-the space between the two collars'18 and 14 only throughthe slots 36 ilrth'e collar 18,"except what little may pass through the small coincident portions of the slots 44 and 42. Furthermore, owing to the closure of lthe slots 46 and 48f of the sleeve 20 and member 24 respectively, water can" now only enter the space between the 'collars 32 and 30 through the `slots 38 of said collar 32 and leave said space and the device by the slots 40 inthe collar 30. It will therefore be seen that as the pressure of the water. below the device inc eases the volume of wat'er that can leave he device is dereased. Furthermore it `will be noted thatall the water that passes through the device must flow through the slots 42`in thesleeve 12 andthat as the pressure ofthe water en-v tering the deviceincreases, thus forcing the closed'endof the member 6 farther and farther up into the bore of the sleeve 12, the

effective ,length of said slots-42 is shortened i more and more'so that lessand less water passes through the device, until, should the vpressure of the water entering the device increase that much, only that portion of the .slots 42-cntained in the collar 14 remainsl frzee for the passage of water, as shown in F1g. 4, closure ofthat portion of said slots being prevented by contact of a shoulder 54 i Provided the Coller 1,18. with the lcwr-end y 'means ofthe sleevel. As the pressure diminishes theparts, under the action of the springsv 16. and: 28,` will regain their initial positions,-

it 'being' clearthat, as the lowof VWater `from 'the device gradually-- decreased4 in proportion as the 'pressure ofthe waterentering the device increased, sonow the iow of water fro the device will gradually increase in prophtion as the pressure ofjthe water I twill therefore be seen that with thev aid-of a regulator embodying 'the present invention thc .Pres- .sure of a fluid on leavingy the regulator -will `remain for all practical purposes the same Vthough the pressure of the fluld entering the regulator' vary. So true is this that a jet or bubble of Water` issuing fromy a p'ipe v connected; to the upper end of a regulator embodying this invention retained substan-v tially thev same height; although the pressure ofthe Water venteringthe regulatorv varied between considerable limits, rapid variation between 15' to 140 pounds pressure being noted-in the Water entering thedevice With-` out producing any perceptible variation in the height of the jet or bubble of water at the exit thereof. B y using-springs of variable strength, the devicecan be rendered more or less sensitive, as willN be readily understood.

L For `facilitating the assembling-I of the defor the passage'of the water instead of or mit .the flow o vice the collar -18 is preferably removable, it beingzheld in place `upon the outerend of the member 6 against4 a shoulder 56 (see Fig.

3)- upon the latter, bya bored nut758 having'v screw-threaded connection with` the 'outer end of said member.

By using slots 36, 38 and 40 provided as describedin the peripheral 4surface of the -collars 18, 32. andA 30 respectively as openings dinary perforations, foreignmatter held in suspension in the -Water flowing through the apparatus is not so .likely to become lodged in said openings, and the movement ofthe collars in the operation of the device tends `to dislodge -any foreign matter from said openings.

Obviously many changes -may be made in the details 'of construction without-departing from the true spirit of the present invention,- which is definitely set forth in the claims.
